I am working on a design that uses an LPC2212 and need to have power consumption minimized. According to the datasheet, the 1.8V draws ~10uA in sleep mode, but I'm seeing 40uA. The EVBA7 comes in at 5uA using same code. And worse, I'm not able to get the 3.3V draw under 1.

Hello, I am experincing a strange problem on a LPC2212. Sometimes, after board power-up, the micro does not start at all and seems to remain in a pseudo-reset state (all pins in high-z). The software execution seems not to start at all, since one of the first thing done is to program some of the GPIO as outputs. I checked the state of the BOOT pins related to RESET pin and power supplies

Hello, We are developing a battery powered application using LPC2212. And we have a strange problem with the core current consumption. After the core went into powerdown mode the core current is about 30uA. Then an external circuit removes 3.3V for the peripherials, but the core current consumption rises to 100uA. Any suggestions?

To reduce power consumption in power down mode, I use PINSEL2 to disconnect the EMC and revert external memory bus to inputs. Since these are on P2 and P3 with internal pullups, I should see 3.3V correct? In actuality, I'm seeing them float around 2.2V. I've tried to reset

For the LPC2212 we have the peripheral clock running at 12.5 MHz. I use timer1 for the heartbeat of a scheduler (see a summary of the code below). I discovered that when I use a prescale value of 12500 (scale back to 1 KHz) my configuration for a timer period of 1 ms is in practise 2 ms (measured over 20 sec). When I use a prescale value of 25 (500 kHz) I do see about 1 ms. Is there some...
